"Well, folks, hockey is back!" she Tweeted on Sunday. "I just lost my purse holder but gained cheering on my hot husband as he kicks butt! #GoPreds."

While supportive of Fisher's career, the lighthearted Underwood, 29, is anything but quiet when it comes to voicing her opinion on what comes with being married to a hockey player.

Last April, when Fisher, 32, and his Nashville Predators – he was traded from the Ottawa Senators in February of 2011 – made it to the NHL playoffs, Underwood was thrilled for her husband's success, but not for his impending playoff beard.

"[The players] all grow out their facial hair during the playoffs," she told PEOPLE last year. "So before they started, I told Mike, 'You need to shave close.' He always looks good with a little stubble, but it's probably going to get out of hand soon."

It will come even sooner this season as Fisher points out on his site: "It's nice to finally be able to put this behind us and we can finally start thinking about hockey again ... It's going to go by really quickly, and before you know it the playoffs will be starting."
